LS50 goes wireless

Quite intriguing, will be interesting to read some reviews.

I'm going to likely order in a pair. Not sure how long it will take to get them, but I'll let you know how they do once in hand.
 
Excellent, that would be great and I would appreciate it.

I would love a comparo vs the Gold Phantoms which cost 2x the price but also has far deeper bass. Active LS50 and subs should be a contender!
 
Purely as a loudspeaker the Phantom is probably no competition for the LS50 as such, with its UniQ tech and all. So it just depends on how good electronics KEF are able to pack into the speaker and how much the electronics are going to mess up the passive LS50's qualities.

The wireless concepts appear really on the rise with reputable players like KEF, Devialet, Dynaudio etc. launching products.

Exactly why I would live to see and preferably HEAR a head to head comparison.
 
The Gold Phantom sounds like pure marketing fluff. 4500 watts without blowing a breaker? Titanium the best material for a tweeter...I guess they haven't heard of Beryllium. Response to 14hz, come on now.
 
The bass is very deep. Its an air pusher design.
Titanium better than Alum...not the absolute best.
Sounds very nice and significantly better than the Silver.
Alum midrange driver is likely a compromise due to heat generated internally.

C/Net agrees with you here:
"The other improvement is that the power has been boosted yet again from a ridiculous 3,000 watts to an absolutely ludicrous 4,500W. This has enabled the designers to wring an extra couple of decibels out of the machine to top out at a rock concert-worthy 108 décibels."

If there's one thing I noted about the performance of the Silver Phantom is that it tended on the bright side of neutral. Based on a short listening test the sound I heard lacked the brightness of the previous model and instead sounded open and nuanced. Nick Cave's "Red Right Hand" had the three-dimensionality I'd heard in "proper" stereo systems and managed to untangle the knotty mass of deep vocals and bass line.
Dead Can Dance's "Yulunga (Spirit Dance)" exhibited plenty of air during the 2-minute opening and then when the shaker egg appeared it sounded incredibly present. It was as if someone was shaking it in the room with us. The drums that accompany the shakers weren't as bombastic as I've heard previously, but I couldn't say without further testing of the Phantom with bassy material whether this was a good or bad thing.

Considering you cannot possibly pull 4500 W out of a 110 V 15 A wall socket, I'd venture to say there is an order of magnitude variance here. 4500 MILLIWATTS, sure. 4500 WATTS, in a small speaker, I'm calling BS. Cannot be done without an industrial-grade electrical circuit.

 Reply: An excellent point. I went to their Tech Specs page for the Gold and it says: Power supply with IEC 90-240 V~50/60Hz. I'm not an electrical guy, but I'm guessing it means that it needs a 240V circuit?

Finally:
We don't know its power consumption. All we know is that the 750w model can run on US NEMA-15 outlets. Remember, the wattage figure is the sound pressure, not electrical. Also, they are described as peak power, not continuous.
 
Their power indication appears indeed to be based on some calculation trick. Even with the base model 750W would otherwise be earth shattering when put to play.

Yes, it seems to be "the equivalent SPL" as what traditional gear of such and such output wattage can do.

Fun little speakers! Definitely a big step up from the TV sound bar!

Just saw a pair in Selfridges in London and the salesman was clueless...didnt even know they had a pair on the floor. He was busy telling me thst some Naim bluetooth bix was better. Of course i laughed and proceeded to educate him.
 
I swapped out the power cables and it sounds even better. I didn't go crazy on cost. I got a hold of Cullen cables and he suggested a set. After a couple of weeks on them, to me, it opened up even more.

Good to know....I've not tried swapping power cables yet.
 
Thanks Bill. I certainly love mine, we were playing them this morning. WAY better than the stock LS50 IMHO.
